Spontaneous volume-change and program-launch in OSX

Cucurbit — Thu, 24 Dec 2009 15:53:51 -0800

Spontaneous volume-change and program-launch in OSX. MacBook Pro, OSX 10.5.8. I was using iTunes to put some stuff on my iPod (I think the only other programs I had pen were Firefox and maybe Preview) when all of a sudden my computer's volume started to increase and decrease spontaneously (complete with the speaker image and volume level indicator on the screen and accompanied by the click sound), and then Front Row opened and closed a couple times. I turned off AirPort, disconnecting from the Internet, but again my volume spontaneously changed. I restarted my computer, keeping it offline, and the same things happened again. Any ideas what's going on? I'm really freaked out. I can't think what it might be; a few people were watching movie trailers on a mac in the same room while it was happening, but I guess that couldn't be relevant, since stuff happened after I disconnected from the network...

It's like a tech question and a bad sitcom plot in one!

How do I either recover my Mac OS X password or else get around needing it? Several years ago, my then-girlfriend's father bought a family pack of OS_X Leopard, and gave one of them to me. A year later, she and I were broken up. About six months after that, my computer crashed, and the genius bar had to replace the hard drive and reinstall everything. This means that the update password was lost from memory, and I never knew it and can't easily find out what it might have been (ex's dad installed Leopard himself).

So now I've gone a year without updating and it's starting to drive me crazy. Not only can I not update OS_X, but I can't install any number of things I'd like to either.

Does anyone know how I can either recover what this password might have been, or work around it so that I don't need a password to update?

Much Thanks, and Happy Christmas/Hannuka/Kwanzaa/Solstice/Festivus/Holidays to you.

I'll wipe my ass with a roll of Intel X-25 SSD drives!

melorama — Mon, 21 Dec 2009 05:48:04 -0800

I need semi-definitive opinions regarding the real-world lifespan of an Intel X-25M Solid State Drive running in a Macbook Pro. I just couldn't pass up a $214 Black Friday deal on an 80GB Intel X25-M (2nd generation) SSD, and am excited to install it into my "early-2008" Macbook Pro (pre-unibody) w/4GB of RAM. My plan is to replace the current system drive (a 500GB 7200RPM Seagate Momentus) with the SSD, and physically relocate the Seagate drive to the Superdrive bay, using the MCE OptiBay kit.

The original plan was to install just the base OS (Mac OS X 10.6.2) to the SSD, then relocate my home folder to the larger Seagate drive. But then I got to thinking I might actually want to have everything in my ~/Library and ~/Library/Application Support/ folders to live on the SSD instead. Because I am a neurotic multitasker (I generally have over 50+ tabs open in Firefox at any given moment, just as a general reference point), my logic tells me that I would see a performance benefit from having the ~/Library folder on the SSD, since all my running applications are constantly reading and writing to this folder. So my new plan is to just leave my homefolder on the SSD, and relocate my iTunes Library, videos, pictures, etc on the Seagate drive.

But as astute followers of SSD technology know, MLC-based SSDs will burn out faster the more often you write to them. I've done a lot of searching, and have found conflicting opinions on whether or not it's a good idea to leave oft-written to system files such as the OS page/swapfile on the SSD drive, because of the accelerated wear this would cause. Because of this, many Windows users simply disable the pagefile (despite recommendations from Microsoft to keep it enabled on an SSD), but this is not a viable option under OS X. Another concern with OS X and SSDs is Spotlight indexing, the disabling of which is simply not something I'm willing to do, given how useful Spotlight is.

So the question is, just how quickly will an SSD (specifically the X25) "burn out" if I keep my Mac's swapfiles, ~/Library/* files, Mail.app mailboxes on it, with Spotlight enabled? I also run Crashplan online backup, which does realtime block-level, encrypted incremental backups of my drives up to the cloud.

Additionally, will the lack of TRIM support in OS X cause a significant slowdown in overall performance (i.e. near spinning-platter speeds) if I run my SSD in this manner?

I don't really expect this 80GB X25 SSD to be a long-term thing. I fully expect the sizes of SSDs to significantly increase in the next 12-18 months, at inversely lower prices, at which point I will almost certainly feel no remorse in buying a new SSD, regardless of the level of wear on my current X25. But if my X25 burns out in 6-10 months, that won't be worth it, either.

What say you, Mac SSD-heads?

The Lurkers Support Me in Email — Mon, 14 Dec 2009 16:14:58 -0800

GUIDPartitionTableFilter: How can I non-destructively change a partition's filesystem type ID in OS X? For some reason (which I'll add at the end so I can get to the point) a partition on my external USB drive is mistakenly flagged as 'Microsoft Basic Data' and not 'Apple_HFS', as shown by diskutil:

$ diskutil list

/dev/disk0

   #:                       TYPE NAME                    SIZE       IDENTIFIER

   0:      GUID_partition_scheme                        *500.1 GB   disk0

   1:                        EFI                         209.7 MB   disk0s1

   2:                  Apple_HFS Macintosh HD            402.5 GB   disk0s2

   3:       Microsoft Basic Data Boot Camp               97.1 GB    disk0s3

/dev/disk3


   #:                       TYPE NAME                    SIZE       IDENTIFIER

   0:      GUID_partition_scheme                        *1.0 TB     disk3

   1:                        EFI                         209.7 MB   disk3s1

   2:       Microsoft Basic Data                         999.9 GB   disk3s2

            ^^^^^^^^^^^^^^^^^^^^ Wrong!

When I plug the disk in or boot up, Snow Leopard complains about not being able to recognize the disk and asking if I want to initialize it. However, if I do mount_hfs /dev/disk3s2 /Volumes/Test the drive is mounted and I can access the filesystem just fine.

How can I change the type back to Apple_HFS? I've looked at the gpt and diskutil man pages but only found info pertaining to creating new partitions, not modifying existing ones.

TOSLINK USB surround sound adapter + Mac OS X?

Blazecock Pileon — Sat, 12 Dec 2009 12:57:24 -0800

What is a good, working surround sound USB adapter for a Mac mini in a home theatre setup, which uses a TOSLINK connector? (I would be using this with DVD Player, iTunes, VLC, QuickTime Player, etc. if that matters for software support.)

Sharing Is Caring?

murtagh — Wed, 09 Dec 2009 17:54:25 -0800

Sharing a printer between an iMac (with printer driver installed) and a Windows laptop without installing any drivers on the laptop: can it be done? I have an iMac running OS X Leopard. My sister is using her work laptop. Unfortunately, her company has disallowed (blocked) installation of any new software on the laptop, which includes printer drivers. We need to share the printer between the iMac and the laptop. The iMac, to which the printer is connected, has the printer drivers installed.

Can the printer be shared between the iMac and the laptop without installing any drivers on the laptop?

The printer is a Canon Pixma MP145.

Please tell me this is possible (or any possible alternatives). Any help would be greatly appreciated!

Open-ended games?

nostrich — Tue, 08 Dec 2009 13:54:40 -0800

I would like to find a computer game with a mechanic that rewards constant play (eg, levelling up). What do you recommend? I enjoy playing games, but they're always over too fast (or I get bored of them). As such, I am constantly on the look out for games that are not over too fast. I've filled the hole somewhat with shmups -- it will take hundreds hours of practise before I master DoDonPachi, and it somehow remains fun no matter how many times I play stage 1 -- but sometimes I don't want to play a shmup (or don't want to drag my gamepad out, or whatever), so I'm looking for more.

The first thing that comes to mind is a game where you level up (eg, World of Warcraft), which would be fine, but caveat: I find repetitive grinding incredibly boring. Same reason I am slowly becoming bored of Elements, despite initial enjoyment. So if it requires grinding, I'm probably not going to enjoy it.

Whatever the mechanism, the game needs to continue to be rewarding indefinitely (or for a very long time, at least).

Couple of other caveats: it would be nice if it could be played for 5 minutes or 5 hours depending on my mood (I love Civ, but sitting down for a game is such a commitment). It needs to either be Flash-based or OS X compatible -- I'm just as open to either, and can be relied upon to have a constant internet connection -- anything that requires Windows is useless to me (not hardcore enough to install Boot Camp/VMWare just for a game). I'm also open to emulation (providing x system has an emulator OS X can run competently, of course). Price isn't a huge concern, but it will take a monumentally awesome game to make me consent to a subscription. I'm pretty flexible on genres, but I will say the Sim-genre games never grabbed me very much (though I'm not sure why, it's been a while), because I know they will be among the first answers.

Feel free to ignore caveats: if I like it enough, I'll make exceptions. The only necessary is that it's open-ended and fun and not Puzzle Pirates (though puzzles are ok!).

Anything come to mind?

Does Cubase Mac FLAC?

motty — Tue, 08 Dec 2009 02:36:44 -0800

How can I make Cubase play nicely with FLAC files on OS X? I'm working on some tunes with a guy living miles away, and want to be able to send him FLAC files instead of WAVs to save bandwidth.

He's using Cubase on OS X and I'm using Ardour on Linux. While I'm happy with doing all the WAV -> FLAC -> WAV conversion myself from the commandline, he's not. Searching Cubase forums hasn't turned up anything useful on FLAC integration, and I don't have OS X or Cubase myself, so I thought I'd ask here.

Does Cubase Just Work with FLAC if it finds the libraries? Is there a Cubase plugin for FLAC that I have failed to find? Will my friend have to get hold of one of the point and click FLAC -> AIF/WAV convertors and mess around with file conversion himself?

Or is there another solution I have not thought of, such as a lossless FLAC alternative that already works with Cubase?

Cheers in advance, hivemind.

Help me bring back my wifi!

COBRA! — Mon, 07 Dec 2009 08:15:02 -0800

I'm having wifi troubles with my MacBook, and the lack of connectivity for the weekend gave me the shakes. Help me before the withdrawal gets worse! The gist: WPA2 Personal network, running on a Netgear router. Been up for a while, played nice with my MacBook (running Snow Leopard) and my wife's XP laptop. Over the weekend, the router rebooted during the setup of a new Roku, and my MacBook abruptly dropped the network; since then, I haven't been able to reconnect, just getting the standard "There was an error trying to join the network [SSID]. Please try again later."

My wife's XP machine still connects with no trouble.

As nearly as I can tell, it seems like my laptop sees the network, but can't recognize it as WPA2 Personal; when I try to connect, the SSID shows up in my saved networks as WPA2 Enterprise. Editing one of the Enterprise instances to Personal with the correct login information doesn't help, nor does manually adding a new Personal instance.

Other things I have tried:

- rebooting the router (multiple times)
- deleting the keychain storing network passwords
- deleting the plist storing network prefs
- deleting and re-adding the entire Airport connection in my network prefs
- reinstalling and updating Snow Leopard (update done with the MacBook connected by ethernet)

Any thoughts/suggestions/ideas?

Help me recover a deleted MySQL database on osx

special-k — Fri, 04 Dec 2009 10:19:16 -0800

Where does MySQL store actual data in Snow Leopard? How would I retrieve a deleted database from a Time Machine backup? MySQL was crashing repeatedly on my Snow Leopard. On the advice of an Apple genius, I nuked the existing install and all its associated directories. I didn't worry much because I do database stuff on my work computer and only keep copies on my laptop.

Turns out that there was one particular database [now nuked] that I spent a whole week cleaning up on my laptop. The desktop only has a really old version of this particular database.

I have regular time machine backups. How do I pluck this database out and restore it?
I cannot for the life of me figure out how to get to the data without going through mysql. Someone suggested looking in /usr/local/mysql/data

I can get to the mysql directory but have no permission to enter the data directory. I could recreate much of this work but it will take forever and I'd rather not. Can someone help?

Unless he's keylogging me, in which case he gets what he deserves, the Grinch. ;)

kathrineg — Thu, 03 Dec 2009 13:51:45 -0800

I need a way to keep a browser state with tabs, cookies, passwords, forms all saved but password-protected and inaccessible. I have Mac OS 10.5.7 and I usually use Firefox, kinda hate Safari. This would be somewhat like Firefox's "Private Browsing" but instead of erasing my settings when I go out of the password-protected browser, it would keep everything ready and waiting.

So it would be like when you go from "private browsing" back to regular browsing, and Firefox restores everything automatically. Except that all the data associated with it would need to be password protected/hidden. No one should be able to access anything by clicking through folders, searching the drives, etc.

Switching logins is too onerous. I have some password protected documents but it's getting really old to move stuff from my browser to there, remember to close the document, etc.

I don't need anything with a force password, or anything completely invisible. It's okay if you can see the program/plugin and tell that I'm keeping something secret. It just needs a password so I can foil a certain Santa-hating member of my household who is adept with computer stuff, without going nuts trying to erase my tracks.

Writer meets arthritis

grumblebee — Thu, 03 Dec 2009 11:18:40 -0800

Mac voice-recognition software for a writer with arthritis. My father's arthritis is making it more and more difficult for him to type. This is hard for him, because he's been a writer for decades (over 25 books and countless articles). He is considering switching to voice-recognition software.

Here are some things to note:

- He is originally from England but has lived in the US since the 1950s. He is a very clear speaker, but his accent is a mix of British (cockney originally) and American.

- He owns a Mac.

- He is not highly computer literate, but he lives in a university town and could find people to help him set things up if necessary. He probably will have trouble if the voice-recognition software itself is overly complicated to use.

I am looking for any advice and experiences with this. What is the state of the art these days? What's available for the Mac? What is the experience like for people who are heavy users?

Looking for a Simple HTML Dingus

interrobang — Mon, 30 Nov 2009 07:59:11 -0800

Is there a very simple, free, standalone OSX application like the HTML Post Opera widget? A dashboard widget would be fine, too; I mostly just want it to run on its own on a PPC computer.

WinXP OEM on a Mac

jrchaplin — Sun, 29 Nov 2009 08:25:10 -0800

I've a WinXP Professional OEM install disc that I'd like to (and tried to) install on VMWare Fusion on my 24-inch iMac (running OS X 10.5). But so far, it's a no-go. Is there some kind of restriction on installing OEM versions of Windows in a virtual environment and/or on a Mac? So far my Google-fu has failed me on this question, but what happens is when I get to the activation key box during install, the key is rejected as invalid. What's weird about this is that attempting to install this same XP Pro disc on an old (circa 2004-05) home-built Windows box works flawlessly.

I bought the disc on Ebay, from a seller who exchanged the first disc I bought from him (It would not load/install on any machine) with a new copy. At first I thought that I got hosed by the seller of the disc; but the subsequent ability to install on a Windows box has me wondering if the problem lies elsewhere.

I had hoped to use the WinXP install on my iMac simply for web development testing; not crazy about spending $200 for Win 7, plus another $40 to upgrade my VMware Fusion install to handle Win 7. I know I could use the old box to do the same, but space is at a premium and I was gonna wipe the old box and donate it to a local non-profit.

Getting my OS X calculator back into the Dashboard

siskin — Thu, 26 Nov 2009 13:58:43 -0800

In OS X Snow Leopard, my calculator has escaped from the Dashboard and is always on my screen, and always on top. How can I send it back to the Dashboard? It's definitely the Dashboard widget calculator, and not another calculator - it's the same orange design, and definitely not the normal OS X standalone calculator. But, rather than being in the Dashboard, it's on the normal screen! It's been like this for all of today, but not before. I can't remember if I had the calculator on the Dashboard before today, but it's not there now.

ps -A shows three DashboardClient processes running - when I kill them, they restart (but any number displayed in the calculator is reset to 0). The calculator comes back after a reboot, too.

It doesn't appear as an option to Force Quit; when I select it the menu bar remains on the last selected application; displaying and hiding Dashboard with F12 shows and hides my other widgets, but has no effect on the calculator; there's no obvious way of closing it.

How can I get rid of it?

My Dream Dual Boot Netbook

lemonfridge — Thu, 26 Nov 2009 13:39:01 -0800

Help me build my perfect netbook! I've had my iBook G4 since I started Uni over 6 years ago, but it's starting to show it's age and things are starting to play up (apart from the battery!)

So I've ordered myself a Samsung NC20 with a 2Gb of RAM upgrade. I'd really like to dual or triple boot between Windows, OSX, and....something.

1. It comes with XP, but I'm tempted to go for a Windows 7 upgrade. Thoughts?

I like OSX and wouldn't mind keeping it an option.

2. I'd like a flavour of Linux or possible the new Google OS. Thoughts?

3. I really like how quickly my current iBook waked up when I open the lid. Can I expect the same thing from my new NC20?

4. Where is the best guide to acheive what I want? I've never dual booted anything before.

Formatting Differences in MS Word on Windows vs Mac

spikeleemajortomdickandharryconnickjrmints — Thu, 19 Nov 2009 08:35:47 -0800

How consistent is MS Office between Windows and OSX? Will using MS Office on my Mac solve this formatting problem I'm having? I'm have a MacBook Pro running Leopard,and I've been using Open Office to write my papers. It's great. I love Open Office (and love that it's free). When I need to turn something in, I just save it in PDF format, e-mail it to myself, then go to a computer lab, check my e-mail, and print off the PDF document. Perfect.

The problem is that I have a professor who needs some documents turned in via e-mail, and they use MS Word. I can save an Open Office document as a Word file (.doc or .docx), and for plain text formatting that's fine, but as soon as an outline or numbered list is created, things look crazy. It seems fine when I save it in Open Office, and it's fine when I then open that document using Open Office, but if the document is opened with MS Word, the formatting is horrible.

I can buy the MS Office suite for Mac at school using my student discount (it's around $35 I think). If I install that, and use Word to create these documents, will they appear the same when my professor opens them using Word, on her Windows computer?

If there will still be differences then I'll skip the $35 and just keep going to the computer lab to tweak things.

If I save a document in MS Word on a Mac and send it to a person using MS Word on a PC, are there formatting differences?

Help with a Mac whose apps all go non-responsive?

mark7570 — Wed, 18 Nov 2009 10:50:54 -0800

Once a week or so, all the applications running on my Mac go into "not responding" mode, one after another. The only way I can recover is to turn off the Mac using the power button. Any ideas? It always happens the same way - a usually well-behaved app, say Mail, stops responding - just shows a spinning beach ball. I force quit, but the app doesn't disappear. The beach ball keeps spinning. Then I switch to another app and it starts spinning. And so on. At that point, here's a screenshot showing what I see when I try to force quit.

This is on a MacPro (the big desktop tower), just a few months old, running 10.5.8. As you can see from the screenshot, there aren't any strange apps being run.

Anyone seen this before, or have suggestions for how to prevent this from happening? It's a really bummer when it occurs.

OS X: How to track down and kill a cron job. Or something.

al_fresco — Sat, 14 Nov 2009 15:09:39 -0800

OS X Unix filter: Please help me find and delete an obsolete cron job on an iMac running Leopard. I'm doing tech support for a small office. A previous provider setup a cron job or something to create an rsync backup to a MacMini server every day at the same time. The backup configuration has changed, but this one job keeps trying to run. I can't find the script to delete it and am getting a bit frustrated.

I've tried

crontab -e - which shows an empty crontab.

I've looked in StartupItems, looked in /usr/bin/, usr/sbin/ for a compiled script, looked in the logs to see if I could see the source of the job, but it doesn't log to system.log or console.log. I did find the log that was set up for the backup, but it doesn't say the path of the original script. I know it's running because it was set up to also send an email to the office administrator. She gets a failure message daily.

I'm pretty sure it's not a LaunchDaemon, as the job was set up by someone who was using old-style tools, and all of the LaunchDaemons I could find were stock OS X.

Any idea how I can track this thing down and kill it for good?

Thanks!

What's the deal with Flash video on OSX? I can't click the play button!

Glum — Fri, 13 Nov 2009 14:12:28 -0800

Why do Youtube (and other flash videos) become unresponsive on my Mac when they are embedded in other sites? [iMac and MacBook Pro, Snow Leopard (and previous OS), Firefox & Safari]

Often, when I come across an embedded YouTube clip (and sometimes videos from other services like Vimeo) on my RSS feed or in a website I am visiting I am unable to click on it successfully. Trying to access the controls (play, pause etc) becomes almost impossible. I have found that if I right click to pull up the Flash menu, but then deselect it, I do then get one chance to click on the Flash object (with it going white in the process).

These objects almost always work perectly if I click through to watch them in their original location.

My browsers have been doing this for several versions, over the last two versions of the OS and the last three versions of Flash, on both my Macs. I have the most recent versions of all software.

I've read that Flash is very unreliable on OSX - with memory leaks etc. - but this doesn't seem to be that (although, of course, I don't actually know what it is).

Any help would be greatly appreciated.

How to bulk rename itunes files from external data source.

jlowen — Thu, 12 Nov 2009 15:10:40 -0800

How can I bulk rename files in itunes according to data contained in a separate file? I have 4000-some .wav files in itunes that are essentially field recordings of people talking. The files are named with a 10 digit unique id number and the date acquired. Example: 1234567890_11122009. In a separate csv file I have the identifying information of the individual with the same unique ID number.

I have rated all 4000 recordings based on quality and want to maintain those ratings, but would like to rename the files to drop the unique ID and instead insert the person's name from the csv file. I.e. 1234567890_11122009 becomes Smith_Mary_123_Fake_Street_Anytown_STATE

Can anyone picture a workflow that would accomplish this mass filename change while still maintaining the ratings?

I use a mac and have a decent understanding of automator, grep, csv files etc, but have no real programming skill. I am willing to convert recordings to a different format (mp3 etc.) if that would help. Any ideas?

Best video codec for embedding into PowerPoint?

limon — Sun, 08 Nov 2009 17:51:55 -0800

I'd like to embed video clips in a PowerPoint presentation. It would need to play correctly on both Windows and OS X. What codec is ideal? My first attempt won't play on Macs.
